Bug ID: 33529
Summary: [MS] Clang crashes emitting IR for "throw" when
_CxxThrowException is defined in the TU
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: unassignedclangb...@nondot.org
Reporter: r...@google.com
CC: llvm-bugs@lists.llvm.org
Consider:
struct _ThrowInfo { int a, b, c, d; };
extern "C" void _CxxThrowException(void *p, _ThrowInfo *e) {}
void f() { throw 53; }
Compiling in the usual way on Windows results in:
Assertion failed: isa<X>(Val) && "cast<Ty>() argument of incompatible type!",
file C:\src\llvm-project\llvm\include\llvm/Support/Casting.h, line 255
